Also known as gram-negative bacteremia and gram-positive bacteremia, sepsis occurs when infectious agents like bacteria or fungi or products of infection like bacterial toxins enter the body, most often through a wound or incision.

Overall, two thirds of the swab cultures were positive for either S. aureus (26 percent), Enterococcus species (44 percent) or various bacterial species from a group known as gram-negative rods (22 percent).

Manipulations simulating enhanced UV-B radiation levels and a doubling of atmospheric CO2 concentration for seven years altered the use of labile carbon substrates by gram-negative bacteria, suggesting a change in community composition.

Manipulations simulating enhanced UV-B radiation levels (equivalent to a 15% reduction in stratospheric ozone levels) and a doubling of atmospheric CO2 concentrations for seven years altered the use of labile C substrates by gram-negative bacteria [64].
